$result = mysql_query("SELECT username, password, email, gold, hp, strength, level FROM users where username=$uid",$db);
while ($userdata = mysql_fetch_array($result, $db))
{

Hi,

You are getting this error because the "}" is missing for the while loop.

BTW, I don't think you require the while loop. because there will be only one record per user.

Cheers,
Girish

agree. Turn this to an 'if' or delete the loop beginning. This way there will be no more a closing bracket missing :D

huh ? I did not change anything.

I closed the (missing) bracket in the only place where I touched something, ie at the end  :

<?
} else echo "failed to get result.<BR>";
?>



please note that the // comment and following lines should not be in the script code ;-)

well, the connect failed.

I don't know what is in the include connect.php, but you should definitely add some error checking in there 8-)

Warning: Supplied argument is not a valid MySQL result resource in C:\apache\htdocs\game\play.php on line 5

<?php

include('connect.php');
$result = mysql_query("SELECT username, password, email, gold, hp, strength, level FROM users where username=$uid",$db);
if ($userdata = mysql_fetch_array($result, $db))
{
[snip]

let's count lines :
1 : <?php
2 :
3 :include('connect.php');
4 :$result = mysql_query("SELECT username, password, email, gold, hp, strength, level FROM users where username=$uid",$db);
5 :if ($userdata = mysql_fetch_array($result, $db))

So the problem is that $result is an invalid linkID, as the error message said. This is specific enough for you ?

This means that the $result failed to return any dataset, so as there is NO ERROR CHECKING in your code, we can only guess that :
-either the query failed (perhaps because of the newlines in the string ? :D )
-either $db is an invalid database reference
-or include('connect.php') did not get it right.

THUS I suggested to write, the one in the other, something more like this :

$linkID=mysql_connect("$dbHost","$dbLogin","$dbPassword") or die ("bad connect".mysql_error());

mysql_select_db($dbName,$linkID) or die ("bad select DB yop ".mysql_error());

$query="select * from $dbTableUsers where id=$locID;";

$result=mysql_query($query,$linkID) or die ("bad query='$query' : error was ".mysql_error());

if ($res=mysql_fetch_array($result)) { // ok, found
      $locnom=$res['nom'];
      // do stuff
} // ok, trouvé
else { // not found

you dont need a while here:

while ($userdata = mysql_fetch_array($result, $db))
{
$username = $userdata["username"];
$passw = $userdata["password"];
$emaila = $userdata["email"];
$gold = $userdata["gold"];
$hitpoints = $userdata["hp"];
$strength = $userdata["strength"];
$level = $userdata["level"];
$pass = base64_encode($passw);
$email = base64_encode($emaila);
?>


should be
userdata = mysql_fetch_array($result, $db);

$username = $userdata["username"];
$passw = $userdata["password"];
$emaila = $userdata["email"];
$gold = $userdata["gold"];
$hitpoints = $userdata["hp"];
$strength = $userdata["strength"];
$level = $userdata["level"];
$pass = base64_encode($passw);
$email = base64_encode($emaila);
?>
